Subject: [PATCH] rhbz#876742 speed up table manipulation in Impress
|
||||
|
||||
It turns out this is not actually a performance problem but an oversight
|
||||
in implementation (or a bug, if you want .-)
|
||||
|
||||
Every manipulation with a table (e.g., move, resize; actually even a
|
||||
selection of the table) leads to creation of a full copy of the table
|
||||
(SdrObject::getFullDragClone()). One of the actions the table copy impl.
|
||||
does is to call sdr::CellProperties::SetStyleSheet() on every cell of
|
||||
the new table. CellProperties is derived from
|
||||
sdr::properties::TextProperties and CellProperties::SetStyleSheet() just
|
||||
passes the call to TextProperties::SetStyleSheet(). This is where the
|
||||
trouble begins :-)
|
||||
|
||||
The SDR representation of a table, SdrTableObj, is derived from
|
||||
SdrTextObj. Because of that, SdrTextObj needs to be able to contain more
|
||||
than one SdrText (because a table needs one for every cell). This is
|
||||
handled correctly by TextProperties. But, because there is no SDR
|
||||
representation of a single cell, CellProperties uses the SdrTableObj as
|
||||
the SDR object it works on. Therefore TextProperties::SetStyleSheet()
|
||||
processes all SdrText objects of the _whole table_, not just a single
|
||||
cell. And this is repeated for every other cell...
|
||||
|
||||
